Can this one be backported to  gcc 8.4:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86521

It fixes errors like:
https://travis-ci.org/akien-mga/godot/jobs/654085724
----
./core/math/vector3.h:40:8: note: candidate: 'constexpr 
Vector3::Vector3(Vector3&&)'

editor/plugins/path_editor_plugin.cpp:214:176: error: call of overloaded 
'Vector3(const Variant&)' is ambiguous
----

The same code builds ok with gcc-7 and gcc-9

And the fix is confirmed with that fix backported on top of gcc-8-20200221
